A protease (also known as a proteinase) is an enzyme protein that has the ability to break down other proteins. A protease has the ability to conduct proteolysis, which begins protein catabolism by hydrolysis of peptide bonds that link amino acids together in a peptide or polypeptide chain forming the protein. This activity of a protease as a protein-digesting enzyme is termed a proteolytic activity. Many well-known procedures exist for measuring proteolytic activity (Kalisz, “Microbial Proteinases,” In: Fiechter (ed.), Advances in Biochemical Engineering/Biotechnology, (1988)). For example, proteolytic activity may be ascertained by comparative assays which analyze the respective protease's ability to hydrolyze a commercial substrate. Exemplary substrates useful in the analysis of protease or proteolytic activity, include, but are not limited to, di-methyl casein (Sigma C-9801), bovine collagen (Sigma C-9879), bovine elastin (Sigma E-1625), and bovine keratin (ICN Biomedical 902111). Colorimetric assays utilizing these substrates are well known in the art (see, e.g., WO 99/34011 and U.S. Pat. No. 6,376,450, both of which are incorporated herein by reference).

Serine proteases are a subgroup of carbonyl hydrolases comprising a diverse class of enzymes having a wide range of specificities and biological functions. Much research has been conducted on serine proteases (e.g., subtilisins), due largely to their usefulness in cleaning and feed applications. Although a number of useful variant proteases have been developed to address needs relating to these applications, there remains a need for improved proteases.

One embodiment provides an isolated subtilisin variant comprising an amino acid sequence comprising a combination of amino acid substitutions at two or more positions selected from:

and S24L-N76D-S78N-S87D-A88S-G118R-Q206Y-Y209W-H249R; wherein said variant has proteolytic activity and each amino acid position of said variant is numbered according to the corresponding amino acid position in the Bacillus amyloliquefaciens subtilisin BPN′ sequence shown in SEQ ID NO:2 as determined by alignment of the variant amino acid sequence with the BPN′ amino acid sequence.

In a still further embodiment, one or more subtilisin variant described herein has 70, 75, 80, 85, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99%, or less than 100% amino acid sequence identity to SEQ ID NO:1, SEQ ID NO:2, or SEQ ID NO:14. In another embodiment, one or more subtilisin variant described herein has one or more improved property when compared to a parent or benchmark protease, wherein the improved property is selected from improved protease activity, improved cleaning performance in detergent, and improved thermostability in detergent.

Another embodiment is directed to a composition comprising one or more subtilisin variant described herein with the proviso that the composition is not an automatic dishwashing composition. In yet other embodiments, the detergent composition is an automatic dishwashing detergent composition, a laundry composition, and/or a hand (manual) dishwashing composition. A further embodiment is directed to a method of cleaning an item or surface in need of cleaning, wherein the method comprises contacting the item or surface with one or more subtilisin variant or one or more composition described herein. A still further embodiment provides an isolated nucleic acid sequence comprising a polynucleotide sequence that encodes one or more subtilisin variant described herein; an expression vector comprising said isolated nucleic acid sequence; and/or a recombinant host cell comprising said expression vector.

FIG. 1 provides an alignment of the mature amino acid sequence of B. lentus subtilisin GG36 (SEQ ID NO:1) and the mature amino acid sequence of B. amyloliquefaciens subtilisin BPN′ (SEQ ID NO:2).

Unless otherwise indicated herein, the subtilisin variants described herein can be made and used via conventional techniques commonly used in molecular biology, microbiology, protein purification, protein engineering, protein and DNA sequencing, recombinant DNA fields, and industrial enzyme use and development. Any headings provided herein are provided for the benefit of the reader and not to limit the various embodiments that are apparent upon reading the specification as a whole. Any definitions provided herein are to be interpreted in the context of the specification as a whole. As used herein, the singular terms “a,” “an,” and “the” include the plural reference unless the context clearly indicates otherwise. Unless otherwise indicated herein, nucleic acids are written left to right in 5′ to 3′ orientation; amino acid sequences are written left to right in amino to carboxy orientation, respectively. Each numerical range used herein includes every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.

Each amino acid position of each protease variant described herein is numbered according to the numbering of the corresponding amino acid position in the amino acid sequence of B. amyloliquefaciens subtilisin protease BPN′ (SEQ ID NO:1) as determined through the FIG. 1 alignment of the GG36 sequence (SEQ ID NO:2) with the BPN′ sequence. For example, the starting amino acid of each amino acid substitution in each subtilisin variant for which the parental protease is GG36 will be as set forth in the GG36 parental sequence, and not as set forth in the BPN′ sequence. That is, reference is made to the BPN′ sequence to identify the position and not the starting amino acid of each substitution contained in one or more subtilisin variant described. Accordingly, a given amino acid sequence, such as the amino acid sequence of a subtilisin variant described herein, can be aligned with the BPN′ sequence using an alignment algorithm such as, e.g., BLAST, MUSCLE, or CLUSTAL described hereinbelow, and an amino acid residue in the given amino acid sequence that aligns (preferably optimally aligns) with an amino acid residue in the BPN′ sequence can be conveniently numbered by reference to the corresponding amino acid residue in the subtilisin BPN′ sequence.

The amino acid substitutions of the one or more subtilisin variant described herein is described using one or more of following nomenclatures: position or starting amino acid:position:substituted amino acid(s). Reference to only a position encompasses any starting amino acid that may be present in a parent or benchmark molecule at that position and any amino acid to which such starting amino acid may be substituted (i.e., the substituted amino acid necessarily excludes the starting amino acid of such parent or benchmark molecule). Reference to a substituted amino acid may be further expressed as several substituted amino acids separated by a foreslash (“/”). For example, X130A/N-209-213 represents a three amino acid substitution combination, wherein X is any starting amino acid at position 130 that can be substituted with an alanine (A) or an asparagine (N); 209 represents a position where any starting amino acid can be substituted with an amino acid that is not the starting amino acid; and 213 represents a position where any starting amino acid can be substituted with an amino acid that is not the starting amino acid. By way of further example, S101F/G/H/TN represents five possible substitutions at position 101, wherein the starting amino acid serine (S) can be substituted with a phenylalanine (F), glycine (G), histidine (H), threonine (T), or valine (V).

“Subtilisin” and “subtilisin protease” refer to any member of the S8 serine protease family as described in MEROPS—The Peptidase Data base (Rawlings et al., MEROPS: the peptidase database, Nucl. Acids Res. 34 Database issue, D270-272 (2006)). As described therein, the peptidase family S8 contains the serine endopeptidase subtilisin and its homologues (Biochem. J. 290:205-218 (1993)). Many Bacillus species (Bacillus sp.) secrete large amounts of subtilisins.

“Protease variant”, “variant protease”, and “subtilisin variant” refer to a protease that differs in amino acid sequence from the amino acid sequence of a reference protease (which may be a parent or benchmark protease) by one or more amino acid, such as by one or more amino acid substitution, deletion, an/or addition. The proteolytic activity of such variant may be determined using procedures well known in the art and/or described herein.

The genus “Bacillus” includes all species within the genus Bacillus, as known to those of skill in the art, including, but not limited to, e.g., B. subtilis, B. licheniformis, B. lentus, B. brevis, B. stearothermophilus, B. alkalophilus, B. amyloliquefaciens, B. clausii, B. halodurans, B. megaterium, B. coagulans, B. circulars, B. lautus, and B. thuringiensis. It is recognized that the genus Bacillus continues to undergo taxonomical reorganization. Thus, it is intended that the genus include species that have been reclassified, including, but not limited to, such organisms as B. stearothermophilus, which is now named “Geobacillus stearothermophilus.” The production of resistant endospores in the presence of oxygen is considered a defining feature of the genus Bacillus, although this characteristic also applies to the recently named Alicyclobacillus, Amphibacillus, Aneurinibacillus, Anoxybacillus, Brevibacillus, Filobacillus, Gracilibacillus, Halobacillus, Paenibacillus, Salibacillus, Thermobacillus, Ureibacillus, and Virgibacillus.

“Polynucleotide” and “nucleic acid,” which are used interchangeably herein, refer to a polymer of any length of nucleotide monomers covalently bonded in a chain. DNA (deoxyribonucleic acid), a polynucleotide comprising deoxyribonucleotides, and RNA (ribonucleic acid), a polymer of ribonucleotides, are examples of polynucleotides or nucleic acids having distinct biological function. Polynucleotides or nucleic acids include, but are not limited to, a single-, double- or triple-stranded DNA, genomic DNA, cDNA, RNA, DNA-RNA hybrid, or a polymer comprising purine and pyrimidine bases. The following are non-limiting examples of polynucleotides: genes, gene fragments, chromosomal fragments, expressed sequence tag(s) (EST(s)), exons, introns, messenger RNA (mRNA), transfer RNA (tRNA), ribosomal RNA (rRNA), ribozymes, complementary DNA (cDNA), recombinant polynucleotides, branched polynucleotides, plasmids, vectors, isolated DNA of any sequence, isolated RNA of any sequence, nucleic acid probes, and primers. In some embodiments, polynucleotides comprise modified nucleotides, such as methylated nucleotides and nucleotide analogs, uracyl, other sugars and linking groups such as fluororibose and thioate, and nucleotide branches. In a particular embodiment, a sequence of nucleotides is interrupted by non-nucleotide components.

“Vector” refers to a nucleic acid construct or polynucleotide construct used to introduce or transfer nucleic acid(s) or polynucleotide(s) into a target cell or tissue. A vector is typically used to introduce foreign DNA into another cell or tissue. A vector generally comprises a DNA sequence that is a transgene and a larger polynucleotide sequence that serves as the “backbone” of the vector. The vector typically serves to transfer genetic information, such as the inserted transgene, to a target cell or tissue so as to isolate, multiply, or express the insert transgene in the target cell or tissue. Vectors include, but are not limited to, plasmids, cloning vectors, bacteriophages, viruses (e.g., viral vector), cosmids, expression vectors, shuttle vectors, and cassettes. A vector typically includes an origin of replication, a multicloning site, and a selectable marker. The process of inserting a vector into a target cell is typically referred to as transfection. The transfection of a cell with a viral vector is typically referred to as transduction. In one embodiment, one or more vector described herein comprises a DNA sequence encoding one or more subtilisin variant described herein (e.g., precursor or mature subtilisin variant) that is operably linked to a suitable prosequence (e.g., secretory, signal peptide sequence, etc.) capable of effecting the expression of the DNA sequence in a suitable host.

“Expression cassette” or “expression vector” refers to a nucleic acid construct or vector generated recombinantly or synthetically for the expression of a nucleic acid of interest (e.g., a foreign nucleic acid or transgene) in a target cell. The nucleic acid of interest typically expresses a protein of interest. An expression vector or expression cassette typically comprises a promoter nucleotide sequence that drives or promotes expression of the foreign nucleic acid. The expression vector or cassette also typically includes other specified nucleic acid elements that permit transcription of a particular nucleic acid in a target cell. A recombinant expression cassette can be incorporated into a plasmid, chromosome, mitochondrial DNA, plastid DNA, virus, or nucleic acid fragment. Some expression vectors have the ability to incorporate and express heterologous DNA fragments in a host cell or genome of the host cell. Many prokaryotic and eukaryotic expression vectors are commercially available. Selection of appropriate expression vectors for expression of a protein from a nucleic acid sequence incorporated into the expression vector is within the knowledge of those of skill in the art.

A DNA construct is an artificially constructed segment of nucleic acid that may be introduced into a target cell or tissue. A DNA construct typically comprises a DNA insert comprising a nucleotide sequence encoding a protein of interest that has been subcloned into a vector. The vector may contain bacterial resistance genes for growth in bacteria and a promoter for expression of the protein of interest in an organism. The DNA may be generated in vitro by PCR or any other suitable technique(s) known to those in the art. In some embodiments, the DNA construct comprises a nucleic acid sequence of interest. In some embodiments, the sequence is operably linked to additional elements such as control elements (e.g., promoters, etc.). The DNA construct may further comprise a selectable marker and may further comprise an incoming sequence flanked by homology boxes. The construct may comprise other non-homologous sequences, added to the ends (e.g., stuffer sequences or flanks). In some embodiments, the ends of the sequence are closed such that the DNA construct forms a closed circle. The nucleic acid sequence of interest, which is incorporated into the DNA construct, using techniques well known in the art, may be a wild-type, mutant, or modified nucleic acid. In some embodiments, the DNA construct comprises one or more nucleic acid sequences homologous to the host cell chromosome. In other embodiments, the DNA construct comprises one or more non-homologous nucleotide sequences. Once the DNA construct is assembled in vitro it may be used, for example, to: 1) insert heterologous sequences into a desired target sequence of a host cell; 2) mutagenize a region of the host cell chromosome (i.e., replace an endogenous sequence with a heterologous sequence); 3) delete target genes; and/or 4) introduce a replicating plasmid into the host. “DNA construct” is used interchangeably herein with expression cassette.

“Plasmid” refers to an extrachromosomal DNA molecule which is capable of replicating independently from the chromosomal DNA. A plasmid is double stranded (ds), may be circular, and is typically used as a cloning vector.

“Introduce”, when used in the context of introducing a nucleic acid sequence into a cell, refers to any method suitable for transferring the nucleic acid sequence into the cell. Such methods for introduction include but are not limited to protoplast fusion, transfection, transformation, electroporation, conjugation, and transduction (see, e.g., Ferrari et al., “Genetics,” in Hardwood et al. (eds.), Bacillus, Plenum Publishing Corp., pp. 57-72 (1989)).

A nucleic acid is “operably linked” with another nucleic acid sequence when it is placed into a functional relationship with another nucleic acid sequence. For example, a promoter or enhancer is operably linked to a nucleotide coding sequence if the promoter affects the transcription of the coding sequence. A ribosome binding site may be operably linked to a coding sequence if it is positioned so as to facilitate translation of the coding sequence. Typically, “operably linked” DNA sequences are contiguous. However, enhancers do not have to be contiguous. Linking is accomplished by ligation at convenient restriction sites. If such sites do not exist, synthetic oligonucleotide adaptors or linkers may be used in accordance with conventional practice.

“Gene” refers to a polynucleotide (e.g., a DNA segment), that encodes a polypeptide and includes regions preceding and following the coding regions as well as intervening sequences (introns) between individual coding segments (exons).

“Recombinant” when used with reference to a cell typically indicates that the cell has been modified by the introduction of a heterologous nucleic acid sequence or that the cell is derived from a cell so modified. For example, a recombinant cell may comprise a gene not found in identical form within the native (non-recombinant) form of the cell, or a recombinant cell may comprise a native gene (found in the native form of the cell) but which has been modified and re-introduced into the cell. A recombinant cell may comprise a nucleic acid endogenous to the cell that has been modified without removing the nucleic acid from the cell. Such modifications include those obtained by gene replacement, site-specific mutation, and related techniques known to those of ordinary skill in the art. Recombinant DNA technology includes techniques for the production of recombinant DNA in vitro and transfer of the recombinant DNA into cells where it may be expressed or propagated, thereby producing a recombinant polypeptide. “Recombination,” “recombining,” and “recombined” of polynucleotides or nucleic acids refer generally to the assembly or combining of two or more nucleic acid or polynucleotide strands or fragments to generate a new polynucleotide or nucleic acid. The recombinant polynucleotide or nucleic acid is sometimes referred to as a chimera. A nucleic acid or polypeptide is “recombinant” when it is artificial or engineered, or derived from an artificial or engineered protein or nucleic acid.

Nucleic acid or gene “amplification” refers to a process by which specific DNA sequences are disproportionately replicated such that the amplified nucleic acid or gene becomes present in a higher copy number than was initially present in the genome. In some embodiments, selection of cells by growth in the presence of a drug (e.g., an inhibitor of an inhibitable enzyme) results in the amplification of either the endogenous gene encoding the gene product required for growth in the presence of the drug or by amplification of exogenous (i.e., input) sequences encoding this nucleic acid or gene product or both. Amplification is a special case of nucleic acid replication involving template specificity. It is to be contrasted with non-specific template replication (i.e., replication that is template-dependent but not dependent on a specific template). Template specificity is here distinguished from fidelity of replication (i.e., synthesis of the proper polynucleotide sequence) and nucleotide (ribo- or deoxyribo-) specificity. Template specificity is frequently described in terms of “target” specificity. Target sequences are “targets” in the sense that they are sought to be sorted out from other nucleic acid. Amplification techniques have been designed primarily for this sorting out.

“Primer” refers to an oligonucleotide (a polymer of nucleotide residues), whether occurring naturally as in a purified restriction digest or produced synthetically, which is capable of acting as a point of initiation of synthesis when placed under conditions in which synthesis of a primer extension product which is complementary to a nucleic acid strand is induced (i.e., in the presence of nucleotides and an inducing agent such as DNA polymerase and at a suitable temperature and pH). A primer is preferably single stranded for maximum efficiency in amplification, but may alternatively be double stranded. If double stranded, the primer is first treated to separate its strands before being used to prepare extension products. In one aspect, the primer is an oligodeoxyribonucleotide. The primer must be sufficiently long to prime the synthesis of extension products in the presence of the inducing agent. The exact length of a primer depends on a variety of factors, including temperature, source of primer, and the use of the method.

“Probe” refers to an oligonucleotide, whether occurring naturally as in a purified restriction digest or produced synthetically, recombinantly or by PCR amplification, which is typically capable of hybridizing to another oligonucleotide of interest. A probe may be single-stranded or double-stranded. Probes are useful in the detection, identification and isolation of particular gene sequences.

“Target”, when used in reference to the polymerase chain reaction, refers to the region of nucleic acid bounded by the primers used for polymerase chain reaction. Thus, the “target” is sought to be sorted out from other nucleic acid sequences. A nucleotide “segment” is a region of a nucleic acid within the target nucleic acid sequence.

“Polymerase chain reaction” (PCR) refers to the methods of U.S. Pat. Nos. 4,683,195; 4,683,202; and 4,965,188, which include methods for increasing the concentration of a segment of a target sequence in a mixture of genomic DNA without cloning or purification. This process for amplifying the target sequence is well known in the art.

“Amplification reagents” refers to those reagents (e.g., deoxyribonucleotide triphosphates, buffer, etc.), needed for amplification except for primers, nucleic acid template, and the amplification enzyme. Typically, amplification reagents along with other reaction components are placed and contained in a reaction vessel (test tube, microwell, etc.).

“Restriction endonuclease” or “restriction enzyme” refers to an enzyme (e.g., bacterial enzyme) that is capable of cutting double-stranded or single-stranded DNA at or near a specific sequence of nucleotides known as a restriction site. The nucleotide sequence comprising the restriction site is recognized and cleaved by a given restriction endonuclease or restriction enzyme and is frequently the site for insertion of DNA fragments. A restriction site can be engineered into an expression vector or DNA construct.

“Homologous recombination” refers to the exchange of DNA fragments between two DNA molecules or paired chromosomes at the site of identical or nearly identical nucleotide sequences. In some embodiments, chromosomal integration is homologous recombination.

A nucleic acid or polynucleotide is said to “encode” a polypeptide if, in its native state or when manipulated by methods known to those of skill in the art, it can be transcribed and/or translated to produce the desired polypeptide. The anti-sense strand of such a nucleic acid is also said to encode the sequence. As is known in the art, a DNA sequence can be transcribed by an RNA polymerase to produce an RNA sequence, but an RNA sequence can be reverse transcribed by reverse transcriptase to produce a DNA sequence.

“Host strain” or “host cell” refers to a suitable host for an expression vector or cassette comprising a DNA sequence of interest. The DNA sequence of interest may express a protein of interest in the host strain or host cell.

A “protein” or “polypeptide” comprises a polymeric sequence of amino acid residues. The terms “protein” and “polypeptide” are used interchangeability herein. Due to the degeneracy of the genetic code, one or more nucleotide sequence may encode one or more subtilisin variant described herein.

“Prosequence” or “propetide sequence” refers to an amino acid sequence between the signal peptide sequence and mature protease sequence that is necessary for the secretion of the protease. Cleavage of the prosequence or propeptide sequence results in a mature active protease.

“Signal sequence” or “signal peptide” refers to a sequence of amino acid residues that may participate in the secretion or direct transport of the mature or precursor form of a protein. The signal sequence is typically located N-terminal to the precursor or mature protein sequence. The signal sequence may be endogenous or exogenous. One exemplary exogenous signal sequence comprises the first seven amino acid residues of the signal sequence from B. subtilis subtilisin fused to the remainder of the signal sequence of the subtilisin from B. lentus (ATCC 21536). A signal sequence is normally absent from the mature protein. A signal sequence is typically cleaved from the protein by a signal peptidase after the protein is transported.

The “mature” form of a protein, polypeptide, or peptide refers to the functional form of the protein, polypeptide, or peptide without the signal peptide sequence and propeptide sequence.

The “precursor” form of a protein or peptide refers to a mature form of the protein having a prosequence operably linked to the amino or carbonyl terminus of the protein. The precursor may also have a “signal” sequence operably linked, to the amino terminus of the prosequence. The precursor may also have additional polynucleotides that are involved in post-translational activity (e.g., polynucleotides cleaved therefrom to leave the mature form of a protein or peptide).

“Wild-type” refers to an amino acid sequence or nucleic acid sequence that is a native or naturally occurring sequence.

“Homologous genes” refers to a pair of genes from different, but usually related species, which correspond to each other and which are identical or very similar to each other. The term encompasses genes that are separated by speciation (i.e., the development of new species) (e.g., orthologous genes), as well as genes that have been separated by genetic duplication (e.g., paralogous genes).

“Homology” refers to sequence similarity or identity, with identity being preferred. Homology can be determined by amino acid sequence alignment, e.g., using a program such as BLAST, MUSCLE, or CLUSTAL. Other techniques are described, for example, in Smith and Waterman, Adv. Appl. Math. 2:482 (1981); Needleman and Wunsch, J. Mol. Biol. 48:443 (1970); and Pearson and Lipman, Proc. Natl. Acad. Sci. USA 85:2444 (1988). BLAST is described by Altschul, et al., “Gapped BLAST and PSI BLAST a new generation of protein database search programs”, Nucleic Acids Res., 25(17):3389-402 (1997); Altschul et al., J. Mol. Biol. 215:403-410, (1990); and Karlin et al., Proc. Natl. Acad. Sci. USA 90:5873-5787 (1993). Software for performing BLAST analyses is publicly available through the National Center for Biotechnology Information. MUSCLE is described by Robert C. Edgar, “MUSCLE: multiple sequence alignment with high accuracy and high throughput”, Nucl. Acids Res., 32 (5): 1792-1797 (2004). Software for performing MUSCLE analyses is available from Biomatters Ltd. The CLUSTAL W alignment algorithm is described by Thompson et al., Nucleic Acids Res, 22:4673-4680 (1994). Default parameters for the CLUSTAL W algorithm include: Gap opening penalty=10.0; Gap extension penalty=0.05; Protein weight matrix=BLOSUM series; DNA weight matrix=IUB; Delay divergent sequences %=40; Gap separation distance=8; DNA transitions weight=0.50; List hydrophilic residues=GPSNDQEKR; Use negative matrix=OFF; Toggle Residue specific penalties=ON; Toggle hydrophilic penalties=ON; and Toggle end gap separation penalty=OFF. In CLUSTAL algorithms, deletions occurring at either terminus are included. For example, a variant with a five amino acid deletion at either terminus (or within the polypeptide) of a polypeptide of 500 amino acids would have a percent sequence identity of 99% (495/500 identical residues×100) relative to the “reference” polypeptide. Such a variant would be encompassed by a variant having “at least 99% sequence identity” to the polypeptide.

The percent amino acid sequence identity of one or more subtilisin variant sequence described herein with a parent or benchmark sequence may be readily obtained by one skilled in the art. The percent amino acid identity shared by sequences of interest can be determined by aligning the sequences to directly compare the sequence information, e.g., by using a program such as BLAST, MUSCLE, or CLUSTAL. For example, the percent amino acid sequence identity of a subject sequence to a query sequence can be calculated by optimally aligning the two sequences and comparing the two optimally aligned sequences over the comparison length. The number of positions in the optimal alignment at which identical residues occur in both sequences are determined, thereby providing the number of matched positions, and the number of matched positions is then divided by the total number of positions of the comparison length (which, unless otherwise specified, is the length of the query sequence). The resulting number is multiplied by 100 to yield the percent amino acid sequence identity of the subject sequence to the query sequence.

“Optimal alignment” or “optimally aligned” refers to the alignment of two (or more) sequences giving the highest percent identity score. For example, optimal alignment of two protein sequences can be achieved by manually aligning the sequences such that the maximum number of identical amino acid residues in each sequence are aligned together or by using software programs or procedures described herein or known in the art. In one exemplary aspect, two polypeptide sequences are deemed “optimally aligned” when they are aligned using defined parameters, such as a defined amino acid substitution matrix, gap existence penalty (also termed gap open penalty), and gap extension penalty, so as to achieve the highest similarity score possible for that pair of sequences. The BLOSUM62 scoring matrix (Henikoff and Henikoff, Proc. Natl. Acad. Sci. USA 89(22):10915 (1992)) is often used as a default scoring substitution matrix in polypeptide sequence alignment algorithms (such as BLASTP). The gap existence penalty is imposed for the introduction of a single amino acid gap in one of the aligned sequences, and the gap extension penalty is imposed for each residue position in the gap. Exemplary alignment parameters employed are: BLOSUM62 scoring matrix, gap existence penalty=11, and gap extension penalty=1. The alignment score is defined by the amino acid positions of each sequence at which the alignment begins and ends (e.g., the alignment window), and optionally by the insertion of a gap or multiple gaps into one or both sequences, so as to achieve the highest possible similarity score.

A nucleic acid or polynucleotide is “isolated” when it is partially or completely separated from other components (such as, but not limited to, e.g., other proteins, nucleic acids, cells, etc.). Similarly, a polypeptide, protein or peptide is “isolated” when it is partially or completely separated from other components (such as, but not limited to, e.g., other proteins, nucleic acids, cells, etc.). On a molar basis, an isolated species is more abundant than are other species in a composition. For example, an isolated species may comprise at least about 50%, 70%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% (on a molar basis) of all macromolecular species present. Preferably, the species of interest is purified to essential homogeneity (i.e., contaminant species cannot be detected in the composition by conventional detection methods). Purity and homogeneity can be determined using a number of techniques well known in the art, such as agarose or polyacrylamide gel electrophoresis of a protein or nucleic acid sample, followed by visualization upon staining. If desired, a high-resolution technique, such as high performance liquid chromatography (HPLC) or a similar means can be utilized for purification of the material.

“Purified” as applied to nucleic acids or polypeptides generally denotes a nucleic acid or polypeptide that is essentially free from other components as determined by analytical techniques well known in the art (e.g., a purified polypeptide or polynucleotide forms a discrete band in an electrophoretic gel, chromatographic eluate, and/or a media subjected to density gradient centrifugation). For example, a nucleic acid or polypeptide that gives rise to essentially one band in an electrophoretic gel is “purified.” A purified nucleic acid or polypeptide is at least about 50% pure, usually at least about 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8% or more pure (e.g., percent by weight on a molar basis). In one embodiment, an enzymatic composition containing one or more subtilisin variant and/or polynucleotide described herein can be enriched for said variant or polynucleotide by applying a purification or enrichment technique that is well-known in the art. A substantially pure subtilisin variant and/or polynucleotide described herein will typically comprise at least about 55%, 60%, 70%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98, 99%, 99.5% or more by weight (on a molar basis) of all macromolecular species in a particular composition.

“Combinatorial mutagenesis” refers to methods in which libraries of nucleic acid variants of a reference nucleic acid sequence are generated. In these libraries, the variants contain one or several mutations chosen from a predefined set of mutations. The methods also provide means to introduce random mutations that were not members of the predefined set of mutations. Some such methods include, for example, those set forth in U.S. Pat. No. 6,582,914 and embodied in commercially available kits (e.g., QuikChange® Multi Site-Directed Mutagenesis Kit (Stratagene)).

“Modified nucleic acid sequence” and “modified gene” are used interchangeably herein to refer to a nucleic acid sequence that includes a deletion, insertion or interruption of naturally occurring (i.e., wild-type) nucleic acid sequence. In some embodiments, the expression product of the modified nucleic acid sequence is a truncated protein (e.g., if the modification is a deletion or interruption of the sequence). In some embodiments, the truncated protein retains biological activity. In alternative embodiments, the expression product of the modified nucleic acid sequence is an elongated protein (e.g., modifications comprising an insertion into the nucleic acid sequence). In some embodiments, a nucleotide insertion in the nucleic acid sequence leads to a truncated protein (e.g., when the insertion results in the formation of a stop codon). Thus, an insertion may result in either a truncated protein or an elongated protein as an expression product.

“Thermostability” refers to the amount of enzymatic activity a protease retains after being exposed to an altered temperature over a given period of time under conditions prevailing during, for example, the proteolytic, hydrolyzing, and/or cleaning process. Altered temperatures include increased or decreased temperatures. In one embodiment, thermostability is determined in the presence of one or more detergent component (e.g., surfactants, chelants, builders, etc) and/or one or more water hardness.

“Cleaning performance” refers to the cleaning activity a protease exhibits under conditions prevailing during the proteolytic, hydrolyzing, and/or cleaning process. In one embodiment, the cleaning performance of one or more subtilisin variant described herein or one or more reference protease may be determined by using one or more cleaning assay for one or more enzyme sensitive stains on an item or surface, such as, e.g., for example, a stain resulting from food, grass, blood, milk, or egg protein. Cleaning performance of a variant or reference protease can be determined by subjecting the stain on the item or surface to standard wash condition(s) and assessing the degree to which the stain is removed by using various chromatographic, spectrophotometric, or other quantitative methodologies. Exemplary cleaning assays and methods include, but are not limited to, e.g., those described in WO 99/34011 and U.S. Pat. No. 6,605,458, as well as those cleaning assays and methods included in the Examples presented below. Cleaning performance can be determined by comparing the subtilisin variant described herein to a reference subtilisin protease in various cleaning assays concerning enzyme sensitive stains, such as, for example, grass, blood, milk, ink or egg as determined by usual spectrophotometric or analytical methodologies after standard wash cycle conditions.

The “cleaning effective amount” of one or more subtilisin variant described herein or reference protease refers to the amount of protease that achieves a desired level of enzymatic activity in a specific cleaning composition. Such effective amounts are readily ascertained by one of ordinary skill in the art and are based on many factors, such as the particular protease used, the cleaning application, the specific composition of the cleaning composition, and whether a liquid or dry (e.g., granular, bar) composition is required, etc.

“Cleaning adjunct material” refers to any liquid, solid, or gaseous material included in a cleaning composition other than the one or more subtilisin variant described herein. In one embodiment, a cleaning composition comprises one or more subtilisin variant described herein and one or more cleaning adjunct material. Each cleaning adjunct material is typically selected depending on the particular type and form of cleaning composition (e.g., liquid, granule, powder, bar, paste, spray, tablet, gel; or foam composition). Preferably, each cleaning adjunct material is compatible with the one or more subtilisin variant described herein.

“Cleaning composition” refers to any composition useful for removing a compound (e.g., undesired compound) from an object, item or surface to be cleaned, including, but not limited, to, e.g., a fabric, fabric item, dishware item, tableware item, glassware item, contact lens, other solid substrate, hair (shampoo) (including human or animal hair), skin (soap or and cream), teeth (mouthwashes, toothpastes), surface of an item or object (e.g., hard surface, such as, e.g., the hard surface of a table, table top, wall, furniture item, floor, ceiling, non-dishware item, non-tableware item, etc.), contact lenses, etc. The term encompasses any material and/or added compound selected for the particular type of cleaning composition desired and the form of the product (e.g., liquid, gel, granule, or spray composition), as long as the composition is compatible with the protease and other enzyme(s) used in the composition. The specific selection of cleaning composition materials are readily made by considering the surface, object, item, or fabric to be cleaned, and the desired form of the composition. Cleaning compositions include compositions used in industrial and institutional as well as household cleaning.

Cleaning compositions include any composition that is suited for cleaning, bleaching, disinfecting, and/or sterilizing any object, item, and/or surface. Such compositions include, but are not limited to, for example, liquid and/or solid compositions (including cleaning or detergent compositions) such as, for example, liquid, tablet, gel, granule, unit dose and/or solid compositions; fine fabric detergent compositions; hard surface cleaning compositions, such as, for example, glass, wood, ceramic and metal counter tops and windows; carpet cleaners; oven cleaners; fabric fresheners; fabric softeners; laundry booster cleaning or detergent compositions; laundry additive cleaning compositions; laundry pre-spotter cleaning compositions; and dishwashing compositions, including hand or manual dishwashing compositions (e.g., “hand” or “manual” dishwashing detergents) and automatic dishwashing compositions (e.g., “automatic dishwashing detergents”).

Cleaning compositions include, for example, granular or powder-form all-purpose or heavy-duty washing agents, especially cleaning detergents; liquid, granular, gel, solid, tablet, unit dose or paste-form all-purpose washing agents, especially the so-called heavy-duty liquid (HDL) detergent or heavy-duty powder detergent (HDD) types; liquid fine-fabric detergents; hand or manual dishwashing agents, including those of the high-foaming type; automatic dishwashing, or dishware or tableware washing agents, including the various tablet, powder, solid, granular, liquid, gel, and rinse-aid types for household and institutional use; liquid cleaning and disinfecting agents, including antibacterial hand-wash types, cleaning bars, mouthwashes, denture cleaners, car shampoos, carpet shampoos, bathroom cleaners; hair shampoos and/or hair-rinses for humans and other animals; shower gels and foam baths and metal cleaners; as well as cleaning auxiliaries, such as bleach additives and “stain-stick” or pre-treat types. In some embodiments, granular compositions are in “compact” form; in some embodiments, liquid compositions are in a “concentrated” form.

“Fabric cleaning compositions” refers to hand and machine laundry detergent compositions including laundry additive compositions and compositions suitable for use in the soaking and/or pretreatment of stained fabrics (e.g., clothes, linens, and other textile materials). Fabric cleaning compositions include composition used in industrial and institutional as well as household cleaning.

“Detergent composition” is used in reference to a composition intended for use in a wash medium for the cleaning of soiled or dirty objects.

“Bleaching” refers to the treatment of a material (e.g., fabric, laundry, pulp, etc.) or surface for a sufficient length of time and/or under appropriate pH and/or temperature conditions to effect a brightening (i.e., whitening) and/or cleaning of the material. Examples of chemicals suitable for bleaching include, but are not limited to, e.g., ClO₂, H₂O₂, peracids, NO₂, etc.

Disclosed herein is one or more subtilisin variant, including, e.g., but not limited to, serine protease variants and subtilisin protease variants, that are particularly well suited to and useful in a variety of cleaning applications. One embodiment is directed to one or more isolated, recombinant, substantially pure, and/or non-naturally occurring subtilisin variant. A further embodiment is directed to one or more subtilisin variant with enzymatic activity. In another embodiment the enzymatic activity is proteolytic activity. In a still further embodiment, the one or more subtilisin variant is a Bacillus sp. subtilisin variant.

Another embodiment provides an isolated subtilisin variant comprising an amino acid sequence comprising a combination of amino acid substitutions at two or more positions selected from:

Such suitable methods include, for example, protoplast transformation and congression, transduction, and protoplast fusion. For example, transformation methods can be used to introduce a DNA construct or vector comprising a nucleic acid encoding a subtilisin described herein into a host cell. Exemplary transformation methods include plasmid marker rescue transformation, which involves the uptake of a donor plasmid by competent cells carrying a partially homologous resident plasmid. Such methods are described, for example, in Contente et al., Plasmid 2:555-571 (1979); Haima et al., Mol. Gen. Genet. 223:185-191 (1990); Weinrauch et al., J. Bacteriol. 154:1077-1087 (1983); and Weinrauch et al., J. Bacteriol. 169:1205-1211 (1987).

In some embodiments, host cells are directly transformed with a DNA construct or vector comprising a nucleic acid encoding a subtilisin variant described herein (i.e., an intermediate cell is not used to amplify, or otherwise process, the DNA construct or vector prior to introduction into the host cell). Introduction of a DNA construct or vector described herein into the host cell includes physical and chemical methods known in the art to introduce a nucleic acid sequence into a host cell without insertion into a plasmid or vector. Such methods include, but are not limited to, for example, calcium chloride precipitation, electroporation, naked DNA, and liposomes. In additional embodiments, a DNA construct or vector is co-transformed with a plasmid, without being inserted into the plasmid. In further embodiments, a selective marker is deleted from the altered Bacillus strain by methods known in the art (see, e.g., Stahl et al., J. Bacteriol. 158:411-418 (1984) and Palmeros et al., Gene 247:255-264 (2000)).

Different geographies have different water hardness. Water hardness is usually described in terms of the grains per gallon (“gpg”) mixed Ca²⁺/Mg²⁺. Hardness is a measure of the amount of calcium (Ca²⁺) and magnesium (Mg²⁺) in the water. Most water in the United States is hard, but the degree of hardness varies. Moderately hard (60-120 ppm) to hard (121-181 ppm) water has 60 to 181 ppm (ppm can be converted to grains per U.S. gallon by dividing ppm by 17.1) of hardness minerals.

Water Grains per gallon Parts per million Soft less than 1.0 less than 17 Slightly hard 1.0 to 3.5 17 to 60 Moderately hard 3.5 to 7.0  60 to 120 Hard  7.0 to 10.5 120 to 180 Very hard greater than 10.5 greater than 180

European water hardness is typically greater than about 10.5 (e.g., about 10.5 to about 20.0) gpg mixed Ca²⁺/Mg²⁺ (e.g., about 15 gpg mixed Ca²⁺/Mg²⁺⁺). North American water hardness is typically greater than Japanese water hardness, and less than European water hardness. For example, North American water hardness is generally between about 3 to about 10 gpg, about 3 to about 8 gpg, or about 6 gpg. Japanese water hardness is typically less than about 4 gpg (e.g., about 3 gpg mixed Ca²⁺/Mg²⁺).

EXAMPLE 1 Methods Performance Index

The performance index (PI) of an enzyme compares the performance of the variant (measured value) with the parent enzyme (theoretical value or measured value) at the same protein concentration. Theoretical concentrations for the parent enzyme can be calculated using the parameters extracted from a Langmuir fit of a standard curve of the parent enzyme. A PI that is greater than 1 (PI>1) indicates improved performance by a variant as compared to a parent or benchmark protease (defined for each analyzed data set), while a PI of 1 (PI=1) identifies a variant that performs the same as the parent, and a PI that is less than 1 (PI<1) identifies a variant that performs worse than the parent.

Protein Purification

Samples were dialyzed overnight against 25 mM MES, pH 5.4, 1 mM CaCl₂ buffer, and loaded on a 30 mL Source 15S column (GE Healthcare) equilibrated with the same buffer. A gradient of 0 to 150 mM NaCl was run, and fractions were collected. Fractions containing target protein were pooled, concentrated, and formulated with 40% Propylene Glycol, and sterile filtered.

HPLC Assay for Protein Determination

For high resolution concentration determinations, high performance liquid chromatography (HPLC) method was performed on protein samples. An Agilent 1100 HPLC equipped with an Agilent 300SB-C8 column was used for protein quantitation. Samples were eluted from the column using a gradient of 0.1% trifluoroacetic acid (TFA) in water and 0.1% TFA in acetonitrile. Absorbance was measured at 220 nm, and peaks were integrated using ChemStation software (Agilent Technologies, USA). The protein concentrations of the samples were calculated based on a standard curve of the purified GG36 protease variant designated JV0001 (SEQ ID NO:14).

Protease Activity Assays

The protease activity of GG36 wild-type (“WT”) (SEQ ID NO:1) (“Parent”) and variants thereof was tested by measuring hydrolysis of dimethyl casein (DMC) or skim milk substrates or by measuring hydrolysis of N-succinyl-Ala-Ala-Pro-Phe p-nitroanilide (suc-AAPF-pNA) colorimetric substrate.

The reagent solutions used for the DMC assay were: 2.5% w/v DMC (Sigma C-9801) in 100 mM sodium carbonate buffer pH 9.5, 0.075% TNBSA (Thermo Scientific) in Reagent A. Reagent A: 45.4 g Na₂B₄O₇.10H₂O in 15 mL 4 N NaOH to reach a final volume of 1000 mL in deionized water. Protease supernatants were diluted in dilution solution: 10 mM NaCl, 0.1 mM CaCl₂, 0.005% Tween-80 to the desired concentration to achieve a linear response during hydrolysis over 3 min. A 384-well microtiter plate (MTP) was filled with 27 μl DMC substrate followed by the addition of 27 μl of TNBSA in Reagent A. 64 of 5 μl diluted protease supernatant was then added with slow mixing. Activity was measured at 405 nm over 3 min using a SpectraMax plate reader in kinetic mode at RT. The absorbance of a blank containing thermally inactivated protease was subtracted from each sample reading. The protease activity was expressed as mOD/min.

The reagent solutions used for the skim milk assay were: 40 mg/mL BD Difco skim milk powder in 100 mM Tris, 0.005% Tween-80, pH 8.6 with 10 gpg hardness. The solution was equilibrated for 1 h before use. Activity was measured at 650 nm over 3 min using a SpectraMax plate reader in kinetic mode at RT. Activity was expressed as mOD/min.

Protease activity was tested by measuring the hydrolysis of N-Succinyl-Ala-Ala-Pro-Phe p-nitroanilide (suc-AAPF-pNA, Sigma: S-7388) colorimetric substrate. The reagent solutions used were: 100 mM Tris-HCl pH 8.6, 0.005% Tween®-80 (Tris buffer) and 160 mM suc-AAPF-pNA in DMSO (suc-AAPF-pNA stock solution). Enzyme supernatants were diluted using a dilution solution (10 mM sodium chloride, 0.1 mM calcium chloride, 0.005% Tween®-80 and 0.02% sodium azide). To prepare a working substrate solution, 1 mL of suc-AAPF-pNA stock solution was added to 100 mL Tris buffer and mixed. A 384-well microtiter plate (MTP) was filled with 50 μL/well of the 1 mg/mL suc-AAPF-pNA working solution and aliquots (5 μL/well) of diluted enzyme supernatants were added to wells of this MTP with slow mixing. Activity was measured by reading absorbance at 405 nm over 3 min using a SpectraMax spectrophotometer plate reader in kinetic mode at room temperature. The absorbance of a blank containing thermally inactivated protease was subtracted from each sample reading. The protease activity was expressed as mOD/min and protease dilutions were targeted to give blank-corrected unstressed protease activities in the range of 5 to 300 mOD/min.

Cleaning Performance in ADW Detergent

Cleaning performance of the GG36 variants was tested relative to Parent using PAS-38 microswatches (egg yolk on polyacryl fabric, aged and colored with carbon black dye, purchased from Center for Testmaterials BV, Vlaardingen, Netherlands) as a read out for dish-based applications. Pre-punched (to fit on MTP), rinsed, and filled swatch-containing MTPs (Corning 3641) were prepared by Center for Testmaterials BV. The cleaning performance of GG36 variants was evaluated under automatic dishwashing applications (ADW) using Composition A (set forth in Table 1 herein below) that was pH adjusted to 11 using 10 mM CAPS. PAS38 swatches were prepared by adding 180 μl 10 mM CAPS buffer of pH 11 to MTPs containing PAS38 microswatches. The MTPs were sealed and incubated in an iEMS incubator for 30 min at 60° C. and 1100 rpm shaking. After incubation, the buffer was removed and the plates were air dried prior to use in the performance assay. The MTPs were filled prior to enzyme addition with Composition A with 19 gpg water hardness (to represent very hard water conditions) for testing at 50° C. The MTPs were filled prior to enzyme addition with Composition A and Composition B with 7 gpg water hardness (to represent moderate water conditions) at 20° C. Water hardness was adjusted by using a stock solution of 15,000 gpg (3:1 Ca:Mg, 1.924 M CaCl₂ and 0.641 M MgCl₂). For the wash conditions, Composition A was diluted to a final concentration of 3.95 g/L for the wash tests and Composition B was diluted to a final concentration of lmL/L.

For the assay, 5-10 uL (10-20 ppm) of diluted enzyme solution was added to each well. The MTPs were sealed then incubated in IEMS shaker for 30 min at 20° C. or 50° C. Following incubation, 160 ul of supernatant was transferred to a fresh MTP (Costar 9017) and absorbance was measured at 405 nm using a SpectraMax plate reader. Absorbance results were obtained by subtracting the value for a blank control (no enzyme) from each sample value (hereinafter “blank subtracted absorbance”). For each condition, a ratio is determined by dividing the blank subtracted absorbance of each enzyme, including the Parent, by the predicted absorbance value of the Parent at the same concentration. This value is determined from a standard curve of purified Parent that was fitted to a Langmuir fit. PI was calculated by dividing the above calculated ratio for each enzyme by the above ratio calculated for the Parent.

Thermostability in ADW Detergent

To measure enzyme stability, Composition A, as dissolved in deionized water to a final concentration of 3.95 g/L at the desired water hardness (either 1 or 19 gpg), and aliquots of GG36 variant were added to reach the desired enzyme concentration. The proteolytic activity of the proteases was subsequently measured before and after a heat incubation step using the DMC protease activity assay described above. The temperature and duration of the heat incubation step were chosen such that the reference protease showed 30% residual activity. The measurements were conducted in: (a) soft water (1 gpg) at stress temperatures ranging from 48° C. to 57° C., and (b) hard water (19 gpg) at stress temperatures ranging from 56° C. to 71° C. % residual activities were calculated by taking a ratio of the stressed to unstressed activity and multiplying by 100. Stability PIs were obtained by dividing the residual activity of the GG36 variant by that of the Parent. As the stability of the variants increased, the Parent was unable to be used as the control for measuring % residual activity due to the large differences in stability between the Parent and the increasingly more stable variants. JV0009, which could be stressed to a similar % residual activity as the other variants, was chosen as the new control variant and subsequently used in place of the Parent to calculate PIs for these variants. To convert the PIs calculated with respect to JV0009 to the Parent, the half-lives of JV0009 and Parent were determined at 1 and 19 gpg. The half-lives were determined by measuring the remaining DMC activity at different time points and then fitting the times points versus the remaining activity to the single exponential decay function. The ratio of calculated half-lives at each water hardness was used to convert the PIs calculated with respect to JV0009 to PIs with respect to Parent. The PIs set forth in Table 4 were converted in this manner from JV0009 to Parent.

Cleaning Performance in Laundry Detergent

Cleaning performance of GG36 variants was tested relative to JV0001 using EMPA-116 microswatches (blood/milk/ink on cotton, purchased from Center for Testmaterials BV, Vlaardingen, Netherlands) as a read out for laundry based applications. The assays were performed using commercially available heavy duty liquid laundry (HDL) detergent TIDE® (Original scent, Procter and Gamble), purchased from local supermarkets in 2016.

To abolish background enzyme activity, the enzymes present in this commercial detergent were inactivated by incubating the detergent at 95° C. for 4 hours in a water bath. Following the heat incubation, the detergent was assayed for any remaining background protease activity using the AAPF activity assay described above protease activity was not detected after the 4-hour heat incubation, demonstrating inactivation of background activity.

Pre-punched (to fit on MTP) swatches in MTP plates (non-binding flat-bottom clear polystyrene 96-well plates, Corning 3641) were prepared by Center for Testmaterials BV, Vlaardingen, Netherlands. These microswatch-containing plates were pre-rinsed by adding 180 uL of de-ionized water to each swatch-containing well and shaking the plates at 25° C. for 15 minutes at 1150 rpm (e.g. in an iEMS incubator/shaker, Thermo Fisher Scientific, Waltham, Mass.). The rinse water was removed and the swatches were then air dried in the plate overnight.

For this assay, the protein concentration in enzyme supernatants was determined by Bradford method using Bio-Rad Protein Assay Dye Reagent Concentrate (Catalog Number 500-0006, Bio-Rad Laboratories, Hercules, Calif.), according to manufacturer's instructions. Briefly, the reagent concentrate was diluted with deionized water to working concentration (4:1 (v/v) ratio of water to concentrate) and aliquots of diluted enzyme supernatants were mixed with the working reagent (1:20 (v/v) ratio of sample to reagent) in each well of a microtiter plate (e.g. non-binding, flat bottom clear polystyrene plate, Corning 3641). The plate was incubated for 10 minutes at room temperature and absorbance at 595 nm was measured in a plate reader spectrophotometer (e.g. SpectraMax Plus 384, Molecular Devices, Sunnyvale, Calif.). The protein concentration in the samples was determined based on the standard curve of purified JV0001 protease.

To test the cleaning performance of enzyme variants, aliquots of enzyme supernatants were added to microswatch-containing MTPs prefilled with the solution of heat-inactivated TIDE® detergent (final detergent concentration 0.78 g/L, diluted using 5 mM HEPES buffer, pH 8.2 and 6 gpg water hardness) to reach a final volume of 180 uL per well, with a final enzyme concentration between 0.5-2.5 ppm. The MTPs were sealed and then incubated in an iEMS incubator/shaker (Thermo Fisher Scientific, Waltham, Mass.) at 25° C. with agitation at 1150 rpm for 30 min. Following the incubation, 100 uL of wash liquor supernatant were transferred to a fresh MTP (e.g. medium binding, flat bottom clear polystyrene plate, Corning 9017) and absorbance was measured at 600 nm in a plate reader spectrophotometer (e.g. SpectraMax Plus 384, Molecular Devices, Sunnyvale, Calif.). The absorbance value of a blank control (no enzyme) was subtracted from the absorbance value of each sample to obtain blank subtracted absorbance results (hereinafter “blank subtracted absorbance”). For each condition, a ratio is determined by dividing the blank subtracted absorbance of each enzyme, including the JV0001 protease by the predicted absorbance value of the JV0001 protease at the same concentration. This predicted absorbance value is determined from a standard curve of purified JV0001 protease that was fitted to a Langmuir fit. Performance Index (PI) was computed by dividing the above calculated ratio for each enzyme by the above ratio calculated for the JV0001 protease.

Thermostability in Laundry Detergent

Protease stability of GG36 variants was evaluated by measuring residual activity of samples after incubation under stress conditions using commercially available heavy duty liquid laundry (HDL) detergent TIDE® (Original scent, Procter and Gamble), purchased from local supermarkets in 2016. To abolish background enzyme activity, the enzymes present in this commercial detergent were inactivated using the protocol described above under “Cleaning Performance in Laundry Detergent” (incubating the detergent at 95° C. for 4 hours in a water bath and demonstrating the absence of background protease activity using the AAPF activity assay).

Heat-inactivated detergent was diluted to 10% w/w in deionized water and aliquots of GG36 variants were added to reach the desired enzyme concentration. The proteolytic activity of the proteases was subsequently measured before and after a heat incubation step, using the AAPF protease activity assay described above. GG36, JV0001, and JV0009 were used as controls and incubation conditions were chosen such that one of the controls displayed 30-60% residual activity. The heat incubation step was conducted for 5 minutes at stress temperatures ranging from 50° C. to 61° C.

The protease-detergent samples were diluted 10-fold in dilution solution (10 mM sodium chloride, 0.1 mM calcium chloride, 0.005% Tween 80, and 0.02% sodium azide) before performing the AAPF activity assay. Unstressed and stressed activity values were determined in triplicate. Residual activities for each replicate were calculated by dividing blank-subtracted stressed activity by the blank-subtracted unstressed activity. These triplicate residual activity measurements were subsequently averaged and multiplied by 100 to express them as % residual activity.

EXAMPLE 2 Cloning and Expression of GG36 Protease Variants

DNA manipulations to generate GG36 variants were carried out using conventional molecular biology techniques (see, e.g., Sambrook et al, Molecular Cloning: Cold Spring Harbor Laboratory Press). An artificial DNA sequence was generated that introduced multiple amino acid modifications into the sequence of GG36 WT to generate the different variants. The nucleotide sequence of the GG36 WT gene is set forth as SEQ ID NO:3. DNA cassettes comprising the B. subtilis aprE promoter set forth as SEQ ID NO:4 and the B. subtilis aprE signal peptide set forth as SEQ ID NO:5 were synthesized. Using techniques known in the art, PCR fragments were assembled using Gibson Assembly to make the final expression cassettes. The amino acid sequence of the aprE signal peptide from B. subtilis encoded by SEQ ID NO:5 is set forth as SEQ ID NO:6.

The expression cassette incorporating the GG36 variants and other elements described above was either integrated into the chromosome of a suitable B. subtilis strain or cloned into the pSB replicating shuttle vector (Babe L M, Yoast S, Dreyer M, and Schmidt B F, “Heterologous expression of human granzyme K in Bacillus subtilis and characterization of its hydrolytic activity in vitro”, Biotechnol Appl Biochem., 27, Pt 2, 117-24, 1998) and transformed into a suitable B. subtilis strain. The pSB vector was derived from pBNppt, which was constructed by cloning the aprE gene fragment into plasmid pBN3. Plasmid pBN3 was constructed by removing the Pstl site in the ampicillin gene from plasmid pBN2. Plasmid pBN2 was a hybrid plasmid of pBR322 and pUB110 with a multiple cloning site from pUC18. DNA fragments comprising B. subtilis expression cassette (set forth as SEQ ID NO:7) and GG36 gene (set forth as SEQ ID NO:3) were amplified by PCR using primers listed on Table 2.

Using techniques known in the art, PCR fragments were assembled using Gibson Assembly (SGI DNA Cat# GA1100-10) to make the final expression cassette. The B. subtilis cells were transformed and grown on agar-solidified LB supplemented with 5 ug/ml chloramphenicol.

To generate GG36 variant samples for biochemical characterization, selective growth of the transformed B. subtilis cells was performed in 96 well MTPs at 32° C. for 96 hours in cultivation medium (enriched semi-defined media based on MOPS buffer, with urea as the major nitrogen source, glucose as the main carbon source, and supplemented with 1% soytone for robust cell growth) in each well. Cultures were harvested by centrifugation at 3600 rpm for 45 min and filtered through Multiscreen® filter plates (EMD Millipore, MA, USA) using a Millipore vacuum system. The filtered culture supernatants were used for the assays described below.

The GG36 protease variants that were generated are listed in Tables 3 and 4 with mutations described relative to GG36 using BPN′ numbering.

EXAMPLE 3 ADW Cleaning Performance And Stability of GG36 Protease Variants

GG36 variants generated as described in Example 2 above were screened in MTP assays (as described in Example 1) to compare their cleaning performance and stability to Parent. Results are shown in Tables 5 and 6. Cleaning performance was measured using Composition A at pH 11, and PAS38 egg yolk soil swatches, at 19 gpg and 50° C. Cleaning performance was measured using Composition A and B at pH 11, and PAS38 egg yolk soil swatches, at 7 gpg and 20° C. Enzyme stability was measured by DMC hydrolysis after stress, either at 19 gpg and temperatures ranging from 56-71° C., or at 1 gpg and temperatures ranging from 48-57° C. The specific activity was measured using skim milk as substrate. The acronym “ND” used throughout the tables means that the value was either not determined, or the results are being omitted because the value obtained was too low to have confidence in the value.

EXAMPLE 4 Laundry Cleaning Performance and Stability of GG36 Protease Variants

GG36 variants generated as described in Example 2 above were screened in MTP assays (as described in Example 1) to compare their cleaning performance and stability to Parent. Results are shown in Tables 7 and 8. Cleaning performance was measured using liquid detergent TIDE® (Original scent, Procter and Gamble), and EMPA-116 microswatches (blood/milk/ink on cotton) at 25° C. Enzyme thermostability in 10% TIDE® liquid detergent was measured by AAPF-pNA hydrolysis before and after a stress incubation for 5 minutes, at temperatures listed in Tables 7 and 8 (i.e. at 50° C., 59° C. and/or 61° C.). The acronym “ND” used throughout the tables means “not determined”. In Tables 7 and 8, cleaning is reported as PI compared to parent, and stability is reported as percent remaining activity after stress.

EXAMPLE 5 Automatic Dishwashing Performance Evaluation of Protease Variants in Automatic Dishwashing Composition Test A

One dose of detergent composition (Composition D), comprising 14.69 g of Composition C and 2.13 g of Composition B, was added to each automatic dishwasher at the opening of the dispenser drawer of each cycle.

The ADW compositions described in Table 9 were tested. When a protease was added to a composition of Table 9, the protease was added on a mgs of active enzyme per detergent dose. The proteases tested include JV0001, JV0008, JV0009, JV0024, and JV0025.

Test Stains

Two test stains were used of 6.5 cm×10 cm melamine tiles soiled with Egg Yolk (DM22) and Egg Yolk Milk (DM32), all supplied by the Centre for Testmaterials (Vlaardingen, The Netherlands).

Test Wash Procedure

TABLE 10 ADW Testing Conditions ADW Machine: General Electric 2100 Machine Cycle: Normal Cycle Main Wash volume: 3.8 L Maximum Water temperature: 52.5° C. Water hardness: 1 gpg (US) Rinse: 1 rinse

Composition C was dosed at 3866 ppm and Composition B was dosed at 553 ppm in a North American automatic dishwashing machine. Two tiles for each stain type were added to each automatic dishwashing machine. Four External replicates were carried out and an average stain removal performance for each stain in each ADW composition set forth in Table 9 was calculated (8 total replicates for each Table 9 composition). The cleaning performance of the Example A Composition (containing no protease enzyme) was taken as a reference for each test to calculate the delta SRI values. The stains were analyzed using image analysis, with results presented below calculated as percentage stain removal, i.e. Stain Removal Index (SRI) for the reference Example Composition A treatments, and change in SRI for each of the Example Composition B (Delta B), C (Delta C), D (Delta D), E (Delta E), and F (Delta F) treatments versus the reference Example Composition A treatments. Tukey's HSD multiple comparison procedure is used in order to control the overall error rate for all pairwise comparisons at 0.05 Stain Removal Index (SRI) is defined as: 0=no removal at all, 100=complete removal.

The performance index was also measured by calculating (the performance of each of the Example C, Example D, Example E and Example F Compositions minus the performance of the Example A Composition) divided by (performance of the Comparative Example B Composition minus the performance of the Example A Composition).

By comparing the samples washed with the composition of Example A (nil protease) with Example B (containing JV0001), C, D, E and F (containing JV0008, JV0009, JV0024 and JV0025, respectively), Table 11 indicates that JV0008, JV0009, JV0024 and JV0025 has improved stain removal performance.

By comparing the samples washed with the composition of example B (containing JV0001) with examples C, D, E and F (containing JV0008, JV0009, JV0024 and JV0025, respectively) taking Example A as the reference (nil protease enzyme), Table 12 indicates that JV0008, JV0009, JV0024 and JV0025 achieve a higher level of stain removal than JV0001.

Test B

One dose of detergent composition (Composition D), comprising 14.69 g of Composition C and 2.13 g of Composition B, was added to each automatic dishwasher at the opening of the dispenser drawer of each cycle.

The ADW compositions described in Table 13 were tested. When a protease was added to a composition of Table 13, the protease was added on a mgs of active enzyme per detergent dose. The proteases tested include JV0001 and JV0148.
